An online quiz from the RACQ has challenged drivers on if they can recall a basic road rule which stumps more motorists than it should.

The insurer posted the quiz question to its Facebook on Wednesday with a picture of a T-intersection containing a keep left sign on the road island.

A yellow car is readying to turn right at the intersection while a green car to the right is readying to turn left.

The question posed to social media users was what once of the cars could legally do.

‘Can the yellow vehicle legally make the right turn at this t-intersection with a keep left sign?’ the question read.

The answer to the question was posted hours after the original post but not many Facebook users were stumped.

‘Yes. No line markings or signs indicating he can’t. The keep left sign is for those continuing straight so they don’t cross to the oncoming traffic,’ one user wrote.

‘Yes as long as the right lane has no oncoming traffic. Give way to your right is one rule that everyone needs to learn even when changing lanes especially on the M1 between GC and Brisvegas,’ another added.

One Facebook user also took the time to commend RACQ on making the effort to reinforce simple road rules that some may forget.

‘These are great questions it reminds drivers of simple road rules keep the coming,’ the thankful user wrote.
